Introduction
------------

This is a Python library for reading and writing BLF files,
a proprietary binary logging format of Vector Informatik GmbH.
BLF files are commonly used in automotive logging and testing scenarios.

Installation
------------

.. code-block:: bash

   pip install vblf

Usage
-----

Reading BLF Files
~~~~~~~~~~~~~~~~~

.. code-block:: python

   from vblf.can import CanMessage, CanMessage2
   from vblf.reader import BlfReader

   # Open a BLF file
   with BlfReader("example.blf") as reader:
       # Iterate through all objects in the file
       for obj in reader:
           print(f"Type: {obj.header.base.object_type.name}")
           print(f"Timestamp: {obj.header.object_time_stamp}")

           # Handle CAN messages
           if isinstance(obj, (CanMessage, CanMessage2)):
               print(f"CAN ID: {obj.id}")
               print(f"Data: {obj.data.hex()}")

Writing BLF Files
~~~~~~~~~~~~~~~~~

.. code-block:: python

   from vblf.can import CanMessage
   from vblf.writer import BlfWriter

   # Create a new BLF file
   with BlfWriter("output.blf") as writer:
       # Create a CAN message
       msg = CanMessage(...)

       # Write the message to the file
       writer.write(msg)
